Qmail / TMDA Problems

Hi,

My first post here. Thanks in advance for any advice.

I'm running qmail with vpopmail and trying to get tmda running but i keep  
getting this error in my logs:

>>> delivery 4907: failure:  
>>> preline:_fatal:_unable_to_run_/root/tmda-1.1.12/bin/tmda-filter:_access_denied/

For the record I used qmailrocks.org to help me with installing the  
various applications.

Also, I have tried setting up qconfirm and got similar permission denied  
errors in case that's a clue.

Another note is that the user vpopmail has no shell account  
(/sbin/nologin). I've tried giving this user a regular shell and that  
didn't work.

Thanks for any help :)
